Integration of solar energy and industrial waste heat into an industrial zone with heat distribution networkand optimization of energy sources for units

Karımı, Sasan
In the context of European Union INSHIP (Integrating National Research Agendas on Solar Heat for Industrial Process) project, solar energy and industrial waste heat integration into two food industry Units are simulated and optimized in Izmir, Turkey. Two Units could be connected by a Heat Distribution Network (HDN) to share energy between them. Unit’s thermal systems simulation and energy sources optimization is done by TRNSYS and MATLAB respectively, to use both software capabilities. In each time interval, initially MATLAB models Configurations’ total fuel cost by nonlinear objective functions. Then it minimizes obtained functions with nonlinear optimization method and finally, based on optimization results, MATLAB controls TRNSYS components to operate Units in optimal condition with minimum cost. In fact, Thermal systems simulation and optimization is done simultaneously in this study. Simulations and optimizations are done for February and June as selected simulation periods. Four different Configurations are defined and investigated in separated sections, to simulate Units with different solar energy or industrial waste heat integration options.
